Description
Technical field
The present invention relates to a kind of test device, specifically a kind of test device of bituminous paving interlayer shearing strength belongs to
Field of road.
Background technology
Bituminous paving is the principal mode of current highway in China, and the quality of its pavement performance directly influences national economy
Development, so the construction and maintenance of bituminous paving are all especially important.Simultaneously to the various diseases of bituminous paving appearance in use
Also it can not be ignored, in the common disease of current bituminous paving, including including passage, Yong Bao, rut, due to structural or material
Caused by the shearing strength problem of material.Therefore, the test for bituminous paving interlayer shearing strength, which just turns into, evaluates bituminous paving
One of important indicator of pavement performance, is particularly important so being measured using simple and effective test device to it.Mesh
Before, bituminous paving interlayer shearing strength mainly passes through direct shear test, oblique scissor test, non-limiting shearing test and pull-out test
Measure, above-mentioned experiment is required to each supporting special fixture and coordinates realization jointly with universal testing machine (MTS), and omnipotent examination
Test machine due to it is expensive cause using unit can not universal adapted, testing equipment is wanted so existing test device is present
Ask high and be difficult to popularization and application, to the not high technological deficiency of actual conditions simulating degree, at present still without a kind of preferable asphalt road
The test device of face inter-layer shearing strength.
The content of the invention
, can conveniently, rapidly, accurately it is an object of the invention to provide a kind of measurement apparatus of bituminous paving interlayer shearing strength
The inter-layer shearing strength for measuring each layer of bituminous paving.
The present invention is achieved by the following technical solutions：
Fixed vertical frame plate is respectively perpendicular in base both sides, fixing transverse frame plate parallel to base on two vertical frame plate tops forms
Firm reaction frame, clamp have with move fixture be mobilizable circular sleeve and be connected by two, outside fastening bolt and
Be fixed on into, clamp tool side on base, align and be placed on clamp tool above and below dynamic fixture, dynamic fixture horizontal direction with it is vertical
One proving ring is respectively set on direction, and two proving ring opposite sides set jack between vertical frame plate and transverse frame plate respectively.
The present invention simulates the vertical load on actual road surface by vertical jack, and being further applied load by level jack makes drip
Blue or green two aspects in road surface are destroyed at Coating combination by shear action, the pressure that jack applies when being destroyed by proving ring
Force value, its shear strength parameter is obtained by calculating.High with actual conditions simulating degree, equipment is simple, easy to operate, and test is accurate
True advantage, is a kind of test device of preferable bituminous paving interlayer shearing strength.
Brief description of the drawings
Accompanying drawing 1 is the main structure diagram of the present invention.
Accompanying drawing 2 be accompanying drawing 1 of the present invention along A-A to top view cross section structural representation.
Description of reference numerals is as follows：Base 1, vertical frame plate 2, transverse frame plate 3, clamp tool 4 moves fixture 5, fastening bolt 6 is very heavy
Top 7, proving ring 8, test specimen 9.
Embodiment
With reference to specific embodiment, the present invention is described in detail with accompanying drawing.
Fixed vertical frame plate 2 is respectively perpendicular in the both sides of base 1, crossbearer is fixed parallel to base 1 on two tops of vertical frame plate 2
The firm reaction frame of the formation of plate 3, clamp tool 4 is two mobilizable circular sleeves and tight by two, outside with dynamic fixture 5
Fixing bolt 6 is formed by connecting, and clamp has 4 sides and is fixed on base 1, and dynamic fixture is aligned about 5 to be placed on clamp tool 4, dynamic
One proving ring 8 is respectively set in the horizontal direction of fixture 5 and vertical direction, two opposite sides of proving ring 8 respectively with vertical frame plate 2 with it is horizontal
Jack 7 is set between frame plate 3.
Base 1 of the present invention, vertical frame plate 2 and transverse frame plate 3 are high-strength steel sheet, and all junctions use welding side
Formula secure weld, the clamp tool 4 is the identical and disconnected from each other circular sleeve of two shapes with dynamic fixture 5, and clamp tool 4 is solid
It is scheduled on another wing base 1 of the proving ring 8 of horizontal positioned, cushion block is provided below in proving ring 8 and the jack 7 of horizontal positioned
It is set to have 4 holding levels with clamp.
Above-mentioned embodiment is a preferred embodiment of the present invention, is not intended to limit the specific reality of the present invention
Right is granted, all any equivalent modifications according to described in institute's patent protection scope of the present invention all should be included in
In the range of present patent application.
The following is specifically used and operating procedure of the invention, help to be even further appreciated that the present invention.
From the random coring of bituminous paving or by laboratory shaping test piece, experiment test specimen is obtained, sample dimensions ginseng is measured
Number, loads clamp tool with moving in fixture by test specimen, adjustment test specimen position, the interlayer of different layers is had and dynamic folder just at clamp
At the gap of tool, fastening bolt is tightened.Adjust proving ring, the jack placed vertically, make proving ring, jack and fix
Test specimen three is centrally located at same vertical line, then fixes this and very heavy peaks on transverse frame plate.According to sample dimensions, it is considered to actual road
Area load σ (specification σ=0.7MPa), calculates the force value P that the jack placed vertically needs to apply1(formula isBy adjusting jack stroke, above-mentioned power P is applied by proving ring1In test specimen, by the dynamometry of horizontal positioned
Ring, jack, which are adjusted to have middle part same level with clamp, highly to be located, and is then fixed this and very heavy is peaked at the vertical frame plate placed vertically
On, adjustment jack stroke makes it just contact, and now pressure indication is 0, next very heavy with 50mm/min speed control
Top is advanced, and can clearly read that the pressure value of test specimen must be acted on proving ring, until test specimen is by shear compression failure, reads failing load
P2.Remove jack, proving ring and test specimen.
